5. Half a dozen competing sorts of two-wheelers will be compared issues mileage upon city roads. Ten users of each two-wheeler are selected at random and data on mileage happen to be collected from their website. After overview, 2 findings for company 2, 1 observation of brand 3 and 3 observations of brand a few are removed from thought. The sample means and standard deviations of usage for the six diverse brands of two-wheelers are then calculated which can be given below. Test at a 5% standard of significance there is no factor in the common mileage with the six designs of two-wheelers under consideration.
